Multi-area control vs single-area simplicity

Frequently asked questions

Do I need a 4-channel TENS unit for one body area?

Not always. A single-area device may be enough for one narrow routine. A 4-channel unit becomes more useful when you want wider coverage or multiple routines.

Is a single-area device easier to use?

Often, yes. Single-area devices can be simpler, while Baoliter offers more flexibility for users who want broader coverage and multiple modes.

Why choose Baoliter over a single-area device?

Choose Baoliter when you want 4-channel control, more pad coverage, rechargeable use, and TENS EMS flexibility for repeated home routines.
